I've heard of cases where defective mechanisms cause the gun to go off when the safety is released. Always treat manipulation of the safety as something that possibly might make the gun go off

I've also heard of at least one case where a cop, while holding a suspect at gunpoint with a cocked semi-auto handgun, tried to "safe" his gun by pressing the decocker. The gun went off while pointing at the perp's head. Oops.

Always treat your handgun's decocker as something that might make it go off, too

I realize that freak things do happen, but just like we all said "Never point your gun at anything you don't intend to shoot." That's always rule number 1, even if the guns unloaded.
